⚡ Circuit Builder & Electricity Explorer

Series vs parallel · Conductors vs insulators · Grades 4–7

🔋 Series Circuit
💡—💡—💡
Components are connected in ONE loop. If one bulb breaks, they ALL go out. Current is the same throughout.
Example: Old Christmas lights
🔀 Parallel Circuit
💡 💡 💡
Components each have their own path. If one bulb breaks, the OTHERS stay lit. Voltage is the same across each branch.
Example: House wiring, modern lights
